Thermal Loads and Restraints

Thermal loads and restraints, except for temperature which is also used in structural studies, are only accessible for thermal studies.

For steady state thermal studies with a heat source, a mechanism for heat dissipation must be defined. Otherwise, analysis stops because the temperatures increase without bound. Transient thermal studies that run for a relatively short period of time do not require a heat dissipation mechanism.

The following types of loads and restraints are available for thermal studies:

  • Temperature (prescribed temperatures)
  • Convection
  • Heat Flux
  • Heat Power
  • Radiation

  • Heat Flux

  • Temperature

    The Temperature PropertyManager lets you define a temperature boundary condition for use with structural and thermal analyses. It also lets you define different initial temperatures to selected entities of your model for use with transient thermal analyses.

  • Convection

    Use the Convection PropertyManager to apply convection boundary condition to selected faces of the model in thermal studies (steady state and transient).

  • Heat Power

    The Heat Power PropertyManager lets you apply heat power to the vertices, edges, faces, and components.

  • Radiation

    The Radiation PropertyManager lets you apply surface to ambient or surface-to-surface radiation.

  • Transient Thermal Stress Analysis

    Using a Design Study, you can automate the procedure to calculate static results based on selected temperature profiles from a transient thermal study.

  • Summary of Thermal Boundary Conditions

  • Interaction of Thermal Studies with Other Studies
